Title:
2022 Arctic Strategic Transportation and Resources project (ASTAR) geotechnical data and sample descriptions: Utqiagvik region (Barrow triangle), North Slope, Alaska
Abstract:
2022 Arctic Strategic Transportation and Resources project (ASTAR) geotechnical data and sample descriptions: Utqiagvik region (Barrow triangle), North Slope, Alaska, Raw Data File 2023-13, provides locations, descriptions, and photos of 83 samples from power-auger holes, surface samples, exposures/outcrops, and soil test pits. During the summer of 2022, geologists from the Alaska Division of Geological & Geophysical Surveys (DGGS) and ASRC Consulting & Environmental Services, LLC (ACES) conducted fieldwork in an area of approximately 12,000 km2 in northwestern Alaska between the communities Utqiaġvik, Atqasuk, and Wainwright in support of a sand and gravel resource assessment for the Arctic Strategic Transportation and Resources (ASTAR) Project. This data collection is released as a Raw Data File with an open end-user license. The data are available from the DGGS website: http://doi.org/10.14509/31011.

Who produced the data set?

  1. Who are the originators of the data set? (may include formal authors, digital compilers, and editors)
  2. Who also contributed to the data set?
    The State of Alaska funded this work as part of the ASTAR Project and through a National Petroleum Reserve-Alaska (NPR-A) Impact Mitigation Grant.

Why was the data set created?

The ASTAR Project is a collaborative effort initiated by the Alaska Department of Natural Resources (DNR) in partnership with the North Slope Borough to identify, evaluate, and advance opportunities to enhance the quality of life and economic opportunities in North Slope communities through responsible infrastructure development.

How was the data set created?

  1. From what previous works were the data drawn?
  2. How were the data generated, processed, and modified?
    Date: 2022 (process 1 of 3)
    Sample collection - Field station location data and sediment samples were collected between July 28 and August 7, 2022, using GPS-enabled tablets running the ESRI ArcGIS Collector app, with a reported horizontal error of approximately 10 m. Latitude and longitude are reported in the WGS84 datum. Sediment sample labels correspond to field station locations. Samples were collected from outcrops, the ground surface adjacent to streams and lakes, and from 7-cm-diameter auger holes drilled to a depth of approximately 3.5 m. All samples were stored in resealable plastic bags. At some locations, we collected a series of samples across a vertical exposure (profile description or auger) to determine changes in sediment character. Bulk composition samples were also collected on the ground surface or at the bottom of water bodies to obtain a representative sample at a given field station site.
    Date: 2022 (process 2 of 3)
    Sample preparation - We cleaned surfaces at soil profiles exposed along bluff, river, and lake margins, allowing us to describe soil and sediment stratigraphy on freshly exposed vertical surfaces. When appropriate, we described sedimentary and pedogenic features using U.S. Department of Agriculture Natural Resources Conservation Service terminology (Schoeneberger, 2012). We collected serial bulk and oriented samples from documented soil horizons for laboratory geotechnical analyses. After data collection, we replaced sediment to restore the outcrop to the fullest extent possible.
    Date: 2022 (process 3 of 3)
    Analytical methods - Data include geotechnical information, descriptions, and photographs (provided elsewhere). We followed conventions used in the Alaska Geotechnical Field Manual where appropriate (Alaska Department of Transportation and Public Facilities [AKDOT&PF], 2007). Attribute information includes: moisture content and color based on six standard Munsell colors (light brown, yellowish-orange, greenish-gray, olive-gray, light gray, and dark gray [Munsell, 1994]); Unified Soil Classification System soil type (USCS) (American Society for Testing and Materials, 2000); maximum grain (clast) size; material (clast) concentration; clast composition (mineralogy or lithology); coarse-grained particle angularity; presence or absence of organics (Schoeneberger and others, 2012); and reaction when treated with 10% hydrochloric acid (HCl) (AKDOT&PF, 2007).
